We're dividing 917497 by 66 
The aim is to understand the frequency of 66 in 917497.

On to step 1:
66 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 66

Advancing to step 2:
91 divided by 66 is 1 with a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 66 away from 91, we end up with 25.
Append the next digit (7) from the dividend to 25 and continue with: 257 / 66

Moving on to step 3:
The number 66 fits into 257 3 times, leaving a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 198 from 257 leaves us with 59.
Include the next digit (4) from the dividend after 59, then repeat: 594 / 66

On to step 4:
If we divide 594 by 66, we get 9 and a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 139.0
Deduct 594 from 594 and we're left with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 66

Going ahead to step 5:
If we divide 9 by 66, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 1390.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 66

Going ahead to step 6:
66 can be fit into 97 1 times, resulting in a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 13901.0
If we subtract 66 from 97, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
66 can be fit into 310 4 times, resulting in a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 13901.4
If we take 264 away from 310, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 8:
The number 66 fits into 460 6 times, leaving a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 13901.46
If we subtract 396 from 460, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 9:
When dividing 640 by 66, we get 9 with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 13901.469
If we subtract 594 from 640, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 10:
460 divided by 66 is 6 with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 13901.4696
If we take 396 away from 460, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 11:
If we divide 640 by 66, we get 9 and a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 13901.46969
The remainder is 46 after subtracting 594 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 12:
66 goes into 460 6 times with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 13901.469696
If we subtract 396 from 460, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 13:
If we divide 640 by 66, we get 9 and a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 13901.4696969
Subtract 594 from 640 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 14:
When dividing 460 by 66, we get 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 13901.46969696
Subtract 396 from 460 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 13901.46969696 with a balance of 6.4e-08.
